It is recommended that the following procedure be performed on a table or other flat surface to support the cartridge
and case in order to avoid the possibility of breaking the cartridge leads.

To replace the cartridge in the10A, 12A, or 14A, proceed as follows:

1. Unscrew and remove the grille (turning counter­clockwise).

2. Gently pull out the old cartridge, being careful not
to break the leads.

3. Using a Phillips screwdriver, remove the screws
which hold the switch in place.

4. Using long-nose pliers, gently pull out the switch,
being careful not to break the leads.

5. Unsolder and remove the leads of the old cartridge
from the switch. Discard the old cartridge.

CAUTION: To prevent damage, a soldering
iron between 25 and 40 watts is
recommended.

6. Solder the lead closest to the RED dot on the new
cartridge (see wiring diagram above) to the termi­nal with the YELLOW lead on the switch.

7. Solder the other lead from the new cartridge to the
terminal with the BLUE lead on the switch.

8. Using long-nose pliers, carefully replace the switch
in the case with the blank terminal on the switch
facing towards the cartridge (to ensure the UP

position is ON), being careful not to pinch the
leads.

9. Placing your finger inside the case to support the
switch, secure the switch with the screws removed
in step 3.

NOTE: Do not overtighten the screws.

10. Gently insert the new cartridge into the case, being
careful not to pinch the leads, and making sure the
foam gasket on the cartridge is above the alumi­num ring.

11. Replace and screw on the grille (turning clock­wise).
